An axle assembly having a gear reduction unit and an interaxle differential unit. The gear reduction unit may be operatively connected to an input shaft and may selectively provide gear reduction to a differential assembly and the interaxle differential unit. The interaxle differential unit may operatively connect the gear reduction unit to the output shaft.

A torque vectoring unit for use with a motor vehicle including a differential unit, a gear arrangement and a clutch system. The gear arrangement is connected to the differential unit and includes a first gear set, a second gear set, a third gear set and a common shaft. The clutch system is selectively connected to the gear arrangement and includes a concentric inner clutch and a concentric outer clutch drivingly to an actuator. The actuator actuates each clutch independently. The first gear set includes an external gear supported on the common shaft and an internal gear selectively in engagement with the outer clutch. The second gear set includes an external gear supported on the common shaft and an internal gear selectively in engagement with the inner clutch. The third gear set includes an external gear coupled to the common shaft and an internal gear coupled to a differential case.

A family of axle assemblies that employ a modular concept to maximize part commonality amongst the several axle assemblies. The axle assemblies have a housing assembly that employs a main housing that is formed from a casting that is common to all of the axle assemblies.

An electromechanical clutch for an electronic limited slip differential constructed in accordance to one example of the present disclosure includes a clutch pack, a first lever, a second lever and an actuator assembly. The clutch pack has first and second sets of clutch plates. The first lever arm is rotatably fixed at a pivot pin. The second lever arm is rotatably fixed at the pivot pin. The actuator assembly is configured to rotatably pivot at least one of the first and second lever arms relative to the other of the first and second lever arms whereby the first and second sets of clutch plates are selectively pressed together to thereby lock the electromechanical clutch.

A torque vectoring system constructed in accordance to one example of the present disclosure includes a differential, a first drive axle, a second drive axle, a first gear train and a second gear train. The first drive axle is operably coupled to the differential. The second drive axle is operable coupled to the differential. The first gear train is selectively driven by the differential and is configured to selectively supply a speed application from the differential to one of the first and second drive axles. The second gear train is selectively driven by the differential and is configured to selectively supply a speed reduction from the differential to one of the first and second drive axles.

A drive device for a vehicle axle of a two-track vehicle, which has an axle differential, the input side of which is drivingly connected to an electric machine and the output sides of which drive on flange shafts leading to the two vehicle wheels. The vehicle axle has a superposition gear with a multi-disk clutch on each side of the vehicle, by which the electric machine can be connected directly to the vehicle wheel flange shaft by bridging the axle differential. The multi-disk clutches can be controlled by a control unit. On each side of the vehicle the multi-disk clutch is assigned a multi-disk brake acting as a vehicle wheel brake, by which vehicle braking processes can be carried out alternatively or in addition to the multi-disk clutch.
